So to resolve our problem we have to add some code in the Rsreportserver.config file that you can find under “Program FilesMicrosoft SQL ServerMSSQL.5Reporting ServicesReportServer”

You can specify rendering extension parameters in the RSReportServer configuration file to override default report rendering behavior for reports that run on a Reporting Services report server. You can modify rendering extension parameters to achieve the following objectives:

Change how the rendering extension name appears in the Export list of the report toolbar (for example, to change “Web archive” to “MHTML”), or localize the name to a different language.

Create multiple instances of the same rendering extension to support different report presentation options (for example, a portrait and landscape mode version of the Image rendering extension).

Change the default rendering extension parameters to use different values (for example, the Image rendering extension uses TIFF as the default output format; you can modify the extension parameters to use EMF instead).
